HSRP Preemption On Standby Router - Required Or Not ?

Often I ask this question to CCNPs during interviews - "Do we require PREEMPT command on HSRP Standby router or not ? "

And often candidates either reply "NO" or looks Struggling.

Although Short answer is "YES". But here is the detailed explanation using a test bed.

For those which are new to HSRP. I would recommend first read following posts from Gr8 CCNP Intructor Chris Bryant, CCIE#12933

CCIE R&S Routing Study Plan - IPv4

Every once in a while I get this request to write a CCIE R&S Routing Study Plan similar to CCIE R&S Switching study plan :

http://deepakarora1984.blogspot.com/2010/03/ccie-r-switching-study-plan.html

So lets list all routing topics and allow me to list my attack plan for each of those starting with RIP today... I'll keep adding for rest soon...

1. RIPv2

2. EIGRP

3. OSPF

4. BGP

5. REDISTRIBUTION

6. Learning each of above mentioned routing protocol from MPLS prospective.

Misc :

1. ODR

2. PBR

3. OER/PFR

4. Understanding CEF & IOS Switching

5. Understanding Load Sharing Vs Load Balancing

6. Protocol independent features

So lets begin with RIP for today :)

  RIP

####

1. INE R&S ATC VODs RIP Lectures 

http://www.ine.com/self-paced/ccie-routing-switching/bootcamps/ccie-routing-switching-advanced-technologies-class.htm

2. Jeff Doyle's TCP/IP Vol 1(2nd Edition) 

Two Chapters Just Talking about RIP along with some very good corner case scenarios. Technically one chapter talks about RIPv1 which is not on blueprint but still a good read to grasp fundamentals.

Make sure you test all RIP labs given in this book along the way.

3. Read about RIP from Ruhann's R&S Handbook :

http://routing-bits.com/handbook-for-rs/

4. Enough Theory ? .... Not yet :) ... Move onto RIP Technology Page

 http://www.cisco.com/en/US/tech/tk365/tk554/tsd_technology_support_sub-protocol_home.html

5. Okay... Enough Theory...Time to get some hands dirty with RIP Labs.

Alternatively you can follow any good R&S workbook vendor's RIP Technology Labs like - INE (www.ine.com) , IP Expert (www.ipexpert.com) Or Narbik (www.micronicstraining.com) ...Whatever works best for you

6. Some important blog posts.

http://ardenpackeer.com/routing-protocols/tutorial-troubleshooting-split-horizon-issues-part-1/

http://ardenpackeer.com/routing-protocols/tutorial-troubleshooting-split-horizon-issues-part-2/

7. Enough ? :)... Not Yet... Lets move to final phase and read through IOS 12.4T RIP configuration & command reference guides along with 12.4 T IOS Independent Feature Guide/Command Ref and make sure next time you know where to find what.

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_rip/configuration/12-4t/irr-12-4t-book.html

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_rip/command/irr-cr-book.html

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_pi/configuration/12-4t/iri-12-4t-book.html

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_pi/command/iri-cr-book.html

8. Though by this time you should be good with RIP troubleshooting as well, but just to add one extra bit, INE R&S Troubleshooting Class On Demand is an excellent resource to prepare for this part.

MPLS VPN Troubleshooting - Bob Calling For Help !!!

Finally after a long gap I am back with my tutorials and labs for learning and fun. Few weeks back I posted MPLS VPN Lab topology, So before explaining it step by step I thought to bring it as challenge for people who already know MPLS from R&S lab prospective and are looking for some troubleshooting stuff on it. So I am going to bring today a MPLS VPN TS challenge for them.

So our old friend BOB was sitting free on monday after noon and then he received an email containing the following topology and two fault tickets.

The topology has got two different MPLS VPNs. One is VPN blue and another is VPN red. VPN blue site 1 should be able to reach VPN blue site 2 and vice versa and same case with VPN RED. But both VPNs shouldn't be able to talk to each other.


Below is the link to download initials for lab along with GNS topology and IOS version details to run it. See if you can help BOB with this problem.


BTW.... Avoid removing configurations completely. Also being a excellent engineer, don't use "sh run" to show your skills.

Got Doom Day Date

Native VLAN Horror - Can you solve the puzzle ?

Around 2 years back there was section called "Resources" on NMC Website. Actually plenty of good documents were out there on different R&S blueprint topics. Some of them were my favorite one. They created some scenarios based on few simple things like "Native VLAN", "SPAN/RSPAN" etc which most of you might be thinking about...ehhh...that's easy stuff and I can do even in sleep :-)


But there is always major difference between "knowing about things" Vs "Knowing things inside out". Though it's quite a lot of hard work one needs to do to achieve "Perfection" but still it's doable.


Without saying anything further let me share on of those interesting scenarios to challenge your understandings :-)


Or what Scott Morris call is "abusing people technically and in exiting new ways" hehehe :-)

Another Good Post on CCIE Preparation - From IEOC

Today while spending some time at InterNetwork Expert Support Community AKA ieoc, I came across yet another good post on CCIE Preparation. IMHO ... A must read kind of stuff.

OSPF Mock Lab 1 - Finally Out

Click Image To Enlarge

As I promised earlier, Finally the I am proud to announce about release of OSPF Mock Lab-1 & Trust me it's not going to be easy one :-)

But on the other hand I won't be able to work on any more Protocol Based Mock lab until I pass my R&S Lab which is scheduled for April End 2011. Reason being is that developing such material takes significant time. The OSPF mock lab was supposed to come out in two parts with around 25-30 Tasks each. But you guys must wait for OSPF Mock Lab 2 now. 

But still I am trying my best to bring entertainment for all readers in terms of learning.

With that being said, here is quick link for downloading list of tasks file. Again I would suggest to use Foxit Acrobat reader incase you guys can't see it properly in Adobe Acrobat reader. The password for PDF file is again - deepakarora

http://www.4shared.com/document/aMZ5tu_-/OSPF_Mock_Lab_1_-_List_of_Task.html 

Logical topology you can see above. For GNS physical topology refer the diagram:

https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKPI1WpViLsaY4fnQLtJLbx-85B5G2cwEEGPP5_YF2J-6Wak-C1ksZtSabWH0eK3CmV4Iqm7wVRnSoYBIP4nR6zYXIJx5MfCqdSJ_wu142sQR7SotHN8E39_aCHDVpumwxcJfgY9cnOyY/s1600/OSPF+Mock+Lab+Topology.png

Here is the quick link to download initial configuration file that you would need for each router. Also I added some troubleshooting. So watch out for that :-)

As your OSPF peerings may not come up easily. For getting solution for any of tasks send me an email at - deepakarora.1984@gmail.com with your comments about Blog and Mock Labs.

RIP Configuration Mock Lab - Final Version Completed

Today I proudly announce Completion of my RIP Mock Lab. It was part of an effort to bring free knowledge to people who can't afford to buy costly CCIE Lab preparation material. I started off this effort around 2 years back as an independent Technical blogger and will continue with that as long as possible.

But it's definitely not an effort against any CCIE Vendor. I truly respect them and their work. It's just my effort to bring something for people from developing countries like India where salaries don't match with Global Standards which makes life pretty tough in-case someone want to go for CCIE.

Hopefully every blog reader will like and Enjoy it. Here is the quick URL for download Lab - Tasks, Diagrams, GNS Topology for Windows & Initials.

OR 

http://hotfile.com/dl/76776402/93ff2ff/RIP_Mock_Lab_-_By_Deepak_Arora.rar.html 
  
However for Solution Guide, I would request you spend little time to write an email to me (@ - deepakarora.1984@gmail.com) with your comments on RIP mock lab and about my blog and efforts (Good or bad).

All files are in secure pdf format with password as - deepakarora (same password for RAR file). Make sure you guys use Primo PDF Viewer software(http://www.primopdf.com/download.aspx)  to open pdf file to avoid any format issue which you may have with Adobe pdf Reader.

EIGRP Challenge Lab 1

Recently I have been asked by friend Hemant to come up with a EIGRP challenge Lab. And here it is... :-)


Here is the topology diagram - Click Image to enlarge

Although I am not gonna through any prize for this one. But don't think it's gonna be easy :-)

Here are the quick requirements: 


1. After Performing Unequal Cost Load Balancing , Make Sure the
    EIGRP traffic share count is 1:1 for both links.


Note: Make Sure you used Initial Configs Provided Below, Although changing interface numbering to match your topology won't hurt :-)


Here are the initials:
